Primary pulmonary meningioma: an unusual cause of a nodule with strong and homogeneous enhancement

Abstract

We report a case of a 61-year-old female with atypical chest pain. The chest CT scan revealed a well-circumscribed large intrapulmonary nodule that showed vigorous and homogeneous contrast enhancement. The nodule was diagnosed as a meningioma after surgery. Metastatic meningioma was excluded by brain and spine MRI scans. Primary pulmonary meningioma usually appears as a solitary well-defined round or lobulated nodule with variable enhancement on CT; this case is unique because of the intense and homogeneous enhancement. Although rare, primary pulmonary meningioma should be considered in the differential diagnosis of a well-defined pulmonary nodule with dense and homogeneous enhancement.
